Recently Zeck informed me that he recently met someone who worked for a SEGA Magazine (not an official one), and they claimed to have a prerelease cart. Now of course, I didn't believe a word of it, but none the less, as he now has a working rom dumper (which I've seen pictures of), he got the cart and dumped it. Unfortunatly it appears to simply be Sonic 1 REV 00. However under closer inspection with File Compare: Code (Text): C:\>fc /b "Sonic The Hedgehog (W) (REV00) [!].bin" "Sonic_The_Hedgehog_678.bin" Comparing files Sonic The Hedgehog (W) (REV00) [!].bin and SONIC_THE_HEDGEHOG_678.BIN 00002613: 8E AE C:\> Now you're probably all thinking he just opened up a Hex editor and changed a byte, but still I thought it was worth posting, just in case anyone else has a Sonic 1 cart with "AE" at $2613. Here's a picture of the cart: Apparently it has the word "review" written on it. And here's the dump.
